Single number fax requires CNG tone detection and notification on the fly which will require changes in IOS land, call manager, the Skinny/TSP interface and, of course, in Unity. The changes in Unity aren't really too tough but the hard part is we need to be notified that a call is now a fax and to do something with it. Further, in the gateway's it can be dicey to "Switch" from a voice to fax services (it's doable on some equipment/loads, not others). Lots of changes across multiple components needed to make this fly and right now I don't think it's even on the CM/IOS roadmap.
that said, the applications team will be releasing a new service you can run on any version of 3.0(x) or later that will handle all IP based inbound faxes without the aid of 3rd party fax server or analog fax cards etc... it'll be pretty cool (and no charge on our side).
This will require seperate DID lines for fax, of course, but it's pretty easy to setup in IOS and on the Unity side and I think will put some smiles on people's faces. I'll post more details in a week or two when we're ready to go to beta... yes, you'll be able to just download this off AnswerMonkey, set it up, configure IOS and you've got inbound fax routing.
more details to come...
